Hello everyone. As a long-time fan of ttrss and instapaper, I forked the ttrss-instapaper plugin and got it functional under ttrss v19.2. I have tested it in my docker containers. Hope you guys enjoy it. The repo is in Github:eko133/ttrss-instapaper-plugin
I had to change param_escape to encodeURIComponent to get it working.
sed -i.bak 's/param_escape/encodeURIComponent/g' instapaper.js
